Northampton Saints have confirmed that Stephen Myler and George Pisi have both signed new contracts with the Aviva Premiership champions.
England fly-half Myler penned his first professional deal with the Saints back in 2006, while Samoa centre Pisi joined the club in 2011.
Tom Stephenson and James Wilson have also extended their stays at Franklin's Gardens.
"We're delighted that all four of these players have decided to stay with us and continue their career at the Saints," director of rugby Jim Mallinder told the club's official website.
"They are all quality players who have shown time and again that they have the ability and composure to compete at the highest level of the sport, and they will remain important members of the squad for years to come."
Northampton are currently two points clear at the top of the Aviva Premiership table.
